Airport Carbon Accreditation Program - Level 3

King County International Airport-Boeing Field is committed to achieving carbon neutral status by 2030 in accordance with the county's Strategic Climate Action Plan.

The Airport Carbon Accreditation Program (ACAP) is an internationally recognized carbon management program with more than 550 participating airports. With seven levels of accreditation, ACAP provides participating airports a systematic path towards achieving their carbon reduction goals.

KCIA has already achieved ACAP Level 2, and in 2024 we will be working to progress to Level 3 certification. Level 3 requires KCIA to create a fuller picture of its carbon footprint by including emissions from other sources, such as flights, aircraft ground movements, vendor vehicles, and more.
